WORK-BENCH.

SPECIFICATION forming part of Letters Patent No. 386,831, dated July 31,1888.

(Xo model.)

To all whom it 11mg/ concern:

Be it known that I, JAMES KELLY, a citizen ofthe United States, residingat Carver,county of Carver, and State of Minnesota, have inventedcertain new and useful Improvements in Combined Tolk-Benches, of whichthe following specification is a full, clear, and exact description,reference being also had tothe accompanying drawings.

This invention relates to the combination, in one machine and on onebase-frame, ofseveral implements; and it consists in the construction,combination, and arrangement of parts, as hereinafter shown anddescribed, and then specifically defined by the claims.

In the drawings, Figurel is a sectional side elevation. Fig. 2 is a planview. Fig. 3 is a cross-sectional elevation on the line x x of Fig. l,looking away from the fan. Fig. 4is an en` larged perspective View ofone of the shavinghorsejaws. Fig. 5 is a rear elevation. Fig. 6 is afront elevation on the line a: x oi" Fig. l, looking toward the fan.Fig. 7 is a perspective view of a section ofthe shaving-horse portion ofthe implement,illustrating the manner of attaching the leather-cuttingblade, Ste. Fig. 8 is a plan view of the bench and parts attachedthereto, showing the tailAstock reversed in position as compared withthe position in Fig. 2 and showing the tool-rest in place. Fig. 9 is aninner view of the fixed cam ofthe tailstock, showing the cavity thereinfor setting saw-teeth. Fig. l0 is atop view of the jaws separate,showing the sockets for adjusting the leather-splitting knife.

A represents the bench proper, formed of wood and supported at its rearend by one or more legs, A2, beneath aseat, A, and at its front end by across-bar, B', connected by its ends to the legs B2 of a table orplatform, B3. Upon the top of this bench A is an inclined plank, A4,connected at one end at a to the bench A and held up away from thesaidbench at the other end by a bridge-block, A5, as shown.

AG is alever passing down through the plank A* and bench A and pivotedat b in the base A and having a long lever-arm, C C2, pivoted at b2 inits lower end. The long arm C of this lever projects out beyond thetable B, and is V provided with afoot-board, C3, while the short arm C2projects backward in the opposite direction, and is provided with across-bar, C2 convenient to the foot ot the operator sitting upon theseat A". A block, A7, having a tapered square hole, c', is shown uponthe seat A, but this will be removable, so that the seat will beunobstructed when it is desired to use it. The use and object oi' thisblock will be explained hereinafter.

The lever A and the long arm of the lever C will be connected by abrace-rod, C, to hold them in lixed relations. On the l'ace ot' theupper end of the lever A is secured a metal plate, D', having a lug, D2,Fig. 1, projecting from its face, and ears or arms D:s D* projectingfrom its sides. \'Vhen the lower end of the lever A is pushed backwardby the foot of the operator, the lug and ears D?, D", and D* are presseddown toward the upper surface of the plank A*,and serve to thus firmlyhold any article which the operator desires to work at. The device thusforms a shaving-horse, to hold any Work on which a drawingknit'e orsimilar implement is to be used.

Upon top of the table B is mounted a fancase, B", the lower part of thecasing and the exit-pipe B5 being formed in the table B, as shown. Thistable is shown formed of castiron, but may be formed of wood, il'preferred.

E is the fan-shaft, and E the fan buckets or blades, the shaft beingsupported from the table B:i by standards E3 E, as shown. The standardE3 is formed with two studs, E E5, each adapted to receive and support adouble internal gear, EG. This gear is provided with a set of largeinternal gear-teeth, (t, adapted to engage with a pinion, El, on theshaft E when the hub ofthe gear E is set on the stud E5, and with a setof small internal gearteeth, d2, adapted to engage with the same pinionwhen the gear is set on the hub E.

In the drawings, the gear EG is shown set on the stud Ef,and with itsteeth d' engaging with the pinion El; but it will be readily understoodthat by merely transferring the gear EG to the stud E" the teeth d willengage with the pinion E7. By this simple arrai'igement the speed of theshaft E may be increased or decreased, as desired.

The hub ofthe fan E" is adapted to be connected to or disconnected fromthe shaft E by ICO a set-screw, e, or other suitable means, as required,so that the shaft E may be used independently of the fan. This fan is tobe used for any of the purposes required aboutaworkshop to produce ablast-as for instance, to supply a blacksmiths forge or for meltingmetals in pots or crucibles. The air is conducted in the ordinary wayfrom the fan-case to the place where the blast is to be applied througha pipe or passage, and the means require no further description here.

The arms E3 of the gear E3 are shown bowed outward to enable them topass over theeud of whichever one of the studs E3 or E3 happens, for thetime being, to he the idle one,and the gear is also shown provided witha handle, E23, by which to operate it.'

The end of the shaft E' opposite the gear E3 is formed with a squaresocket, g', forming or adapted to receive a mandrel inwhich a drill,lathecenter, emery-wheel, or other implement or tool may be placed. Theouter surface of this socket g is shown formed into a belt-pulley, fromwhich a belt, g2, may be led down th rough the table B3 and aroundanother pulley on a shaft, F2, journaled in brackets F3 F4 from the baseA or other part of the machine.

F3 is a large balance-wheel on the shaft F2;

`and F3 is a drum on the same shaft,adapted to carry the lower sectionof a band-saw, F2, the upper portion of' the saw being borne by a pulleyor drum, F3, supported above the t-able by a spring arm or standard, F.This springarm F23 is provided with a rod, F, connecting it with` thetable B3 by a nut, F22, on its upper end, so that the tension of the sawmay be regulated. The turning around of the nut F22 also forces thespring-arm downward for the removal of the saw. A removable slide, F23,will be arranged in the table B3, by which the saw F7 may be removed andinserted.

A clamp adapted to support a saw while being 1ed,or pieces of harness orother work while being sewed, is shown set by a tapered leg, G', in theend of the plank A". This clamp consists of two jaws, G2 G3, pivotedtogether at h', and adapted to be held together by a strap, G, fastenedto a cross-bar, G3, in thejaw G3, and passing through jaw G2, and thencedownward to the foot of the operator, or fastened to the lower end ofthe lever A3, or to any other suitable part of the machine. Through thetwo arms ofthe jaw G2 are formed holes t' to receive a rod, H, of ahead, H2, the latter provided with a curved face, H3, adapted to bepressed against the article which the drill or other implement in thesocket g' is acting upon. On opposite sides of the head H2 are formedrecesses K K2, the ends of the recesses next the face H3 being curved,as

at k3, and the ends of the recesses next the rod i H being pointed, asat 7a4. The upper end of the lever A3 and the plate D' are formed andadapted to embrace the head H between the recesses k k2, and the plateDis also provided with pointed portions m', adapted to rest against thecurved portions 7c3 of the head H2,

and also provided with curved portions of" hollows m2, in which thepointed portions k* of the head H2 fit. By this simple arrangement thecurved motion of the lever A3 imparts a horizontal movement to the headH2. The points m act upon the curves k3 to push the head H2 toward thesocket g, and the curves m2 act upon the points k2 to push the head H2away from the socket when the motion of the lever A3 is reversed.

vrlhe rod H, sliding back and forth through the elamparms G2, keeps thehead H2 and face H3 in a horizontal plane, While the peculiar manner ofconnecting the head H2 and lever A3 insures the action of the latterupon the former without any cramping or straining from their distinctlines of movement.

The end of t-he rod H opposite to the head H2 will be pointed, so thatit forms a backcenter to hold a piece of wood in the socket g', oragainst a face-center therein,when it is desired to use the implementasaturning-lathe.l Vhen the rod H is thus to be employed, the clamp inwhich it is mounted is to be reversed in position from the positionshown in Figs. 1 and 2, which is readily effected by inserting thetapered leg G in the opposite direction in its socket in the plank At.

Attached to the table B3.alcngside the standard E2, is a forkedstandard, L, in which one end of a tool rest will be supported, whilethe other end of the tool rest will be supported on a small lug, n', onthe base of the clamp G3 G2, and will be bolted fast to the clamp. Bythis means a tool-rest for use when the machine is used as aturning-lathe will be provided.

In the drawings, the lug n is shown on the opposite side of the clampfrom the support L; but when the lug n is to be used the mere reversalofthe clamp G3 G2 will bring itin the right position.

As before stated, a removable block, A2, is shown upon the seat A3,which is intended to form a support for the clamp G3 G2 when a longerpiece is to be turned or otherwise acted upon than the space between thesocket g and the end of the plank A4 will permit.

t' is a small lug on the side of one of the arms of the jaw G3 of theclamp,th rough which a set-screw, t2, is shown tapped and formed withits inner end triangular to form a saw-set. When thus used, the saw willbe inserted between the jaws G3 G2,wi.th its teeth downward and restingupon a small lug or support, t3, Fig. 3. The jaw G3 is then opened andclosed to cause the end of the set-screw t2 to press ICO IIS

against the saw-teeth and set them to any re- Y the point in the jaw G2opposite t-he set-screw t2, in which thesaw-teeth will be pressed whenacted upon by the set-screw.

In Fig. 7 is shown a perspective view of a lportion of the plank A", andthe upper end of the lever A, and the plate D', illustrating stillanother feature of my invention, consisting in a sharp blade, M,attached to the side of the lever A6 or plate D and adapted to form, inconjunction with asharp-edged plate, M2, on the plank A", a shear-likecutting implement which is rendered operative by the movement of thelever A5. This will be found very convenient in cutting thin metallicsubstances, &c. The blade M is shown with its outer end cut out at u.This portion u isintended to be thinner and sharper than the remainderof the knife and will be used to cut straps or other similar substances.

On the side of the base of the clamp G3 G2 is shown a projection, G, toform a small anvil, and inserted into this anvil I have shown a smallupright knife, o, which Will be found very convenient to use in cuttingleather into straps or strings.

By forming a series of holes in the anvil in which to insert the knifev, or by inserting a block of the proper width between the knife and theclamp, the width of the strap or string to be cut can be regulated.

By placing the rod H through the clamp and drawing the leather being cutaround the rod the latter forms a guide to the leather and insures aneven and uniform cut.

The manner of applying the strip of leather to cut out the straps orstrings is shown in Fig. 3, which represents the leather doubled aroundthe rod H', so as to be drawn around and under the same in contact withthe knife c, the rod thus holding the leather to the knife and forming aguide to the Same. The

width of the straps or strings is determined by CCL the distance betweenthe knife and the edge of the jaw G2.

Vhen used as a drill or turning-lathe, the fan will be disconnected fromits shaft, the latter then revolving loosely therein.

Having described my invention and set forth its merits, what I claimisl. The combination,with a work-bench having a work-plank thereon, of alathe mandrel or chuck mounted on a frame secured to the bench, atail-stock mounted on the plank removable aud reversible in position, alever pivoted to the bench and adapted to move the tail-center to theWork, and a treadle for operat-ing the said lever, all arranged inrelation to one anothersnbstautially as herein set forth.

2. The combination, with a Work-bench having a work-plank thereonprovided with a socket, of a lathe tail-stock fitted in the saidplank-socket removable and reversible therein and provided withclamp-jaws, and a lathe tail-center sliding in one of the jaws of theclamp, substantially as herein set forth.

3. The combinationvithawork-bench having a Work-plank thereon providedwith a socket, of a lathe tail stock fitted in the said plank socket, alathe tail-center slidingin the said tail-stock, and a leather'splittingknife inserted in an anvil on the tail-stock, the said tail-center beingadapted to act as a guide to the leather split by the said knife,snbstantially as and for the purpose herein set forth.

In testimony whereof I have hereunto set my hand in presence of t'wosubscribing Witnesses.
